For my application, I plan on having two nRF24L01+ Modules communicating with each other. They will each be placed in plastic enclosures and need to communicate over no more than 3-4 meters with the potential for people to walk between the enclosures.

From any experience with the chip antenna module (https://www.sparkfun.com/products/691), does anybody know if these boards will be ok or will I need to look at using a different antenna arrangement from another board using the nRF24L01+.
